Charlie Sheen Passese Drug Tests in His In-Home Rehab

Charlie Sheen has been clean since he went off the rails two weeks ago in his 36-hour romp with porn stars -- and he has the drug test results to prove it.

Sources directly connected to Sheen tell us Charlie has passed two drug tests since he began his in-home rehab -- one taken this morning and the other last week.

Charlie has a team of addiction specialists working with him at his home, some of whom he has known for 20 years. The lead specialist is nationally known and someone both Warner Bros. and CBS signed off on.

The two drugs test results are being forwarded on to Warner Bros., which is monitoring Charlie's progress to determine when "Two and a Half Men" can go back into production.

Sources say Charlie "feels great," is actually enjoying his newly-found and hopefully not temporary sobriety and is "itching to get back to work as soon as possible."
